我的 rails4 应用程序使用 Bower 来管理前端依赖项。唯一不由 Bower 管理的 js 是 jQuery，因为 Rails 默认通过 jquery-rails gem 包含它。
“突然”我的开发环境停止工作，因为经过一些更新，出于某种原因，bower 将 jquery 版本锁定为 3.0.0，如 bower.json 文件所述：
masciugo@masciugcbookpro ~/dev/v/hr_dashboard $ r bower:list
I, [2016-06-23T12:58:33.549334 #5308] INFO -- : Celluloid 0.17.3 is running in BACKPORTED mode. [ http://git.io/vJf3J ]

查看各个库bower.json文件，它们都没有设置 jquery 的上限，因此下载并使用了最后一个。实际上eonasdan-bootstrap-datetimepicker不适用于 jquery3，因为它使用 .size ()方法。所以我想知道我可以强制使用较低的 jQuery 版本。我最终从 gemfile 中删除了 jquery-rails 并手动添加了 jquery（和 jquery-ujs），并指定了 bower 版本：
{
"lib": {
"name": "bower-rails generated lib assets",
"dependencies": {
// "threex" : "git@github.com:rharriso/threex.git",
// "gsvpano.js" : "https://github.com/rharriso/GSVPano.js/blob/master/src/GSVPano.js"
}
},
"vendor": {
"name": "bower-rails generated vendor assets",
"dependencies": {
"jquery": "<2",
"jquery-ujs": "<2",
"bootstrap": "3.3.4",
"eonasdan-bootstrap-datetimepicker": "4.17.37",
"bootstrap-validator": "0.9.0",
"moment": "2.13.0",
"underscore": "1.8.3",
"react-geosuggest": "1.9.1",
"pubsub-js": "1.5.3",
"spin.js": "2.3.2",
"jquery-ui": "1.10.4",
"es6-shim": "0.34.4",
"classnames": "2.2.3",
"react-bootstrap": "0.26.4",
"humps": "1.0.0",
"bootstrap-horizon": "0.1.0"
}
}
}
获得：

这是一个可接受的解决方案吗？理想情况下，我会在清单 js 文件中指定版本，但我从未见过。我应该如何处理这种情况？
